• ### Advanced Probability Theory for Biomedical Engineers

This is the third in a series of short books on probability theory and random processes for biomedical engineers. This book focuses on standard probability distributions commonly encountered in biomedical engineering. The exponential, Poisson and Gaussian distributions are introduced, as well as important approximations to the Bernoulli PMF and Gaussian CDF. Many important properties of jointly Gaussian random variables are presented. The primary subjects of the final chapter are methods for determining the probability distribution of a function of a random variable.

• ### Đề tài " On the hardness of approximating minimum vertex cover "

We prove the Minimum Vertex Cover problem to be NP-hard to approximate to within a factor of 1.3606, extending on previous PCP and hardness of approximation technique. To that end, one needs to develop a new proof framework, and to borrow and extend ideas from several ﬁelds. 1. Introduction The basic purpose of computational complexity theory is to classify computational problems according to the amount of resources required to solve them. In particular, the most basic task is to classify computational problems to those that are eﬃciently solvable and those that are not. ...

• ### Towards a Thermodynamic Theory for Ecological Systems

This volume has two first authors because it is a result of very intensive teamwork between the two authors. We have had three brainstorm meetings, each of approximately one week’s duration. There have been numerous pingpong games (questions–answers–new proposals etc.) on the Internet. All the chapters have major contributions from both of us. We hope that the volume therefore demonstrates a synergistic effect, reflecting the positive teamwork that is behind the volume.

• ### Percolation theory in research of oil-reservoir rocks

In reality, the reservoir rock space is a very complex metamerism; however when caculating according to the common way, in many cases, we consider the void structure in the rocks as similar fractal, and use suitable statistical approximate formula to demonstrate the space in form of effective homogene. When researching the layers, we take the rock samples from one layer with different collector parameter. To get a parameter value (grain density, porosity, permeability, saturation etc.

• ### Báo cáo khoa học: "Reducing Approximation and Estimation Errors for Chinese Lexical Processing with Heterogeneous Annotations"

tation schemes in different projects are usually different, since the underlying linguistic theories vary and have different ways to explain the same language phenomena. Though statistical NLP systems usually are not bound to speciﬁc annotation standards, almost all of them assume homogeneous annotation in the training corpus.

• ### Báo cáo khoa học: "A COMPUTATIONAL THEORY OF DISPOSITIONS"

Informally, a disposition is a proposition which is preponderantly, but no necessarily always, true. For example, birds can fly is a disposition, as are the propositions Swedes are blond and Spaniards are dark. An idea which underlies the theory described in this paper is that a disposition may be viewed as a proposition with implicit fuzzy quantifiers which are approximations to all and always, e.g., almost all, almost always, most, frequently, etc. For example, birds can fly may be interpreted as the result of supressing the fuzzy quantifier most in the proposition most birds can fly. ...

• ### Electronics - Theory and Design of Electrical and Electronic Circuits

All the designs that become are not for arming them and that works in their beginning, but to only have an approximated idea of the components to use. To remember here one of the laws of Murphy: " If you make something and works, it is that it has omitted something by stop ".The calculations have so much the heuristic form (test and error) like algoritmic (equations)and, therefore, they will be only contingent; that is to say, that one must correct them until reaching the finished result.

• ### HPLC for Pharmaceutical Scientists 2007 (Part 5)

High-performance liquid chromatography (HPLC) is a separation tool par excellence for the analysis of compounds of wide polarity. Since its inception approximately four decades ago, HPLC has revolutionized numerous disciplines of science and technology. Among the various modes of HPLC, reversed-phase and normal-phase chromatography (NPC) are employed most commonly in separation. Normal-phase chromatography was the ﬁrst liquid chromatography mode, discovered by M. S.

• ### EXACT SMALL SAMPLE THEORY IN THE SIMULTANEOUS EQUATIONS MODEL

Statistical procedures of estimation and inference are most frequently justified in econometric work on the basis of certain desirable asymptotic properties. One estimation procedure may, for example, be selected over another because it is known to provide consistent and asymptotically efficient parameter estimates under certain stochastic environments.

• ### LASER PULSES – THEORY, TECHNOLOGY, AND APPLICATIONS

This book discusses aspects of laser pulses generation, characterization, and practical applications. Some new achievements in theory, experiments, and design are demonstrated. The introductive chapter shortly overviews the physical principles of pulsed lasers operation with pulse durations from seconds to yoctoseconds. A theory of mode-locking, based on the optical noise concept, is discussed. With this approximation, all paradoxes of ultrashort laser pulse formation have been explained.

• ### SUPERCONDUCTIVITY – THEORY AND APPLICATIONS

Superconductivity was discovered 1911 by Kamerlingh Onnes. During the last century, the history of superconductivity has been full of theoretical challenges and practical developments. In 1986, the discovery of Bednorz and Müller of an oxide superconductor with critical temperature (Tc) approximately equal to 35 K, has given a novel impetus to this fascinating subject. Since this discovery, there are a great number of laboratories all over the world involved in research of superconductors with high Tc values, the so-called “high-Tc superconductors”....

• ### Recursive macroeconomic theory, Thomas Sargent 2nd Ed - Chapter 4

Chapter 4 Practical Dynamic Programming 4.1. The curse of dimensionality We often encounter problems where it is impossible to attain closed forms for iterating on the Bellman equation. Then we have to adopt some numerical approximations. This chapter describes two popular methods for obtaining numerical approximations.
